Hello there, I am currently planning to install CentOS 7.3 onto a new laptop, Lenovo Y530 to run my video management software actually.

I am very concern if the drivers will be affected, especially the network cards.
On the https://wiki.centos.org/HowTos/Laptops/, I do not see the laptop there but if any other users can validate for me, that would be great!

I understand your point but will the 7.3 version run fine on the Y530 Lenovo laptop?

Only 7.6 is supported. 7.3 is over 3 years out of date and has numerous high severity security vulnerabilities. It is not safe to run unless you are operating in a closed environment and you never plug a network cable into it - and even then it probably still has local exploits present. In addition, new hardware support is added at each point release.

Just use 7.6 and regularly run yum update so that you stay up to date.

CentOS 5 died in March 2017 - migrate NOW!
